Multidisciplinary Approach to Pain Management

MDT for Pelvic Pain - Defining Foe & Force

Chronic Pelvic Pain (CPP): Non-cyclical pain in pelvic structures >6 months. Impacts quality of life, daily function. MDT essential due to multifactorial nature, addressing diverse pain contributors.

• Core MDT Members & Roles (📌 GPPS - "Good Pain Physicians Save")
  • Gynaecologist: Diagnoses/treats gynaecological pathologies.
  • Pain Specialist: Manages complex pain; pharmacotherapy, interventions.
  • Physiotherapist: Addresses musculoskeletal dysfunction, pelvic floor rehabilitation.
  • Sychologist: Manages psychological impact (anxiety, depression), coping strategies.

⭐ Chronic pelvic pain is defined as non-cyclical pain perceived in structures related to the pelvis of at least 6 months duration.

MDT for Pelvic Pain - Sleuthing Pelvic Pain

• Comprehensive History:
  • Pain: SOCRATES (Site, Onset, Character, Radiation, Associated symptoms, Timing, Exacerbating/Relieving factors, Severity).
  • Red flags: e.g., new-onset post-6 months menopause bleeding, unexplained weight loss, persistent fever.
  • Psychosocial: Hospital Anxiety and Depression Scale (HADS), Brief Pain Inventory (BPI).
• Physical Examination:
  • Abdominal: Assess for masses, tenderness, guarding.
  • Pelvic: Bimanual and speculum examination for organomegaly, tenderness, discharge, lesions.
  • Musculoskeletal: Identify trigger points, assess for Carnett's sign.
• Investigations:
  • Basic: Urine analysis (dipstick, microscopy, culture), high vaginal & endocervical swabs.
  • Imaging: Transvaginal Ultrasound (USG) is first-line. MRI selectively for complex cases or inconclusive USG.
  • Diagnostic Laparoscopy: Key for endometriosis, adhesions; assess role and limitations.

    ⭐ Diagnostic laparoscopy, while key for conditions like endometriosis, may be negative in up to 40% of women with CPP, highlighting the need for a broader diagnostic view.

• Utility of Tools:
  • Pain diaries: Track pain patterns, severity, and impact on daily life.
  • Validated questionnaires: e.g., McGill Pain Questionnaire, Pelvic Pain Assessment Form.

MDT for Pelvic Pain - Multi-Modal Mayhem

A multidisciplinary team (MDT) approach is vital for chronic pelvic pain (CPP), combining multiple therapeutic modalities.

• Pharmacological Management

  • Analgesics:
    • NSAIDs, Paracetamol.
    • Opioids (cautious, short-term for acute flares).
  • Hormonal Therapy (for cyclical pain, endometriosis, adenomyosis):
    • Combined Oral Contraceptive Pills (COCPs).
    • GnRH analogues (e.g., Leuprolide); consider add-back HRT.
  • Neuromodulators (for neuropathic pain):
    • TCAs: Amitriptyline (10-25mg nocte initially).
    • Gabapentinoids: Gabapentin (300mg OD/TDS initially), Pregabalin. 📌 Mnemonic for Neuromodulators: "TAG team for Nerves" (TCAs And Gabapentinoids)

• Non-Pharmacological Management

  • Physiotherapy:
    • Pelvic floor rehabilitation, TENS.
    • Myofascial release.
  • Psychological Therapies:
    • CBT, ACT, mindfulness.
  • Interventional Procedures:
    • Trigger point injections (local anaesthetic +/- steroid).
    • Nerve blocks (e.g., pudendal).

• Integrative Approaches (with evidence context)

  • Yoga, Acupuncture.

• Surgical Options (Last resort, for specific pathologies like severe adenomyosis)

  • Laparoscopy (diagnostic & therapeutic).
  • Hysterectomy.

⭐ A combination of amitriptyline for neuropathic pain and pelvic floor physiotherapy is often more effective than either modality alone in managing CPP.

High‑Yield Points - ⚡ Biggest Takeaways

• Chronic Pelvic Pain (CPP) requires a Multidisciplinary Team (MDT) for effective management.
• MDT includes Gynecology, Pain Medicine, Physiotherapy, and Mental Health specialists.
• The biopsychosocial model is central to understanding and treating CPP.
• Pelvic floor physiotherapy and Cognitive Behavioral Therapy (CBT) are cornerstone non-pharmacological treatments.
• Analgesic ladder for CPP: NSAIDs, TCAs, SNRIs, gabapentinoids.
• Interventional techniques (e.g., nerve blocks, neuromodulation) for refractory pain.
• Patient education and shared decision-making are crucial for adherence and outcomes.
